Specifically, yourself as a GM. Take a good look at yourself, and answer the following questions:

1) What is your favorite style of game to run (Fantasy, Sci-Fi, Horror, etc)?

2) What do you feel are your best qualities when it comes to GMing a game?

3) What do you feel are some of your worst habits as a GM? What do you feel like you need to work on?

4) What do you focus on the most as a GM? A deep plot? A challenge in gameplay? Or truthfully, just everyone’s enjoyment (as long as everyone’s happy, you’re happy)?

5) Has a player during a game ever surprised you with their player’s actions? Something you didn’t expect? What happened? Did it turn out for the better and make things more interesting, or did it all get screwed up?
